Problems solved by technology

Some studies have also suggested that plasma miRNA changes in patients with pancreatic cancer when they are diagnosed, but this change often occurs in the late stage of the disease and cannot be used for early diagnosis

Abstract

The invention discloses application of specific lectin in identification of pancreatic cancer based on a saliva glycoprotein sugar chain structure and a related product. The specific lectin is dividedinto an up-regulation group and a down-regulation group; the upper regulation group is any one or any combination of lectin ECA, PHA-E, GSL-I, LCA, RCA120, ACA, MAL-I and PHA-E + L, and the lower regulation group is any one or any combination of lectin Jacalin, MAL-II, SJA, MPL, PTL-II, DSA, PWM and SNA; the identification basis is as follows: for a detected saliva sample, if the expression of the glycoprotein carbohydrate chain structure identified by the up-regulation group is significantly up-regulated and the expression of the glycoprotein carbohydrate chain structure identified by the down-regulation group is significantly down-regulated, the corresponding subject is indicated to be a pancreatic cancer patient.

Description

technical field [0001] The invention relates to a related product for identifying pancreatic cancer based on the sugar chain structure of sialoglycoprotein. Background technique [0002] Pancreatic cancer (PC) is a malignant tumor with insidious onset, rapid progression, poor curative effect, short median survival time, and extremely poor prognosis. It is known as the "king of cancers". With the improvement of residents' living standards and the increase of clinical detection rate, the incidence of pancreatic cancer has shown an increasing trend year by year in recent years, becoming an important factor threatening the health of residents. In 2018, there were about 459,000 new cases of pancreatic cancer in the world, and about 432,000 deaths. It is the seventh leading cause of cancer death, and it is predicted that it will even surpass breast cancer and become the third leading cause of death among malignant tumors. Due to the lack of effective screening indicators and almo...
